This study investigated the effect of metaconceptual teaching interventions on students' understanding of force and motion concepts. A multimethod research design including quasi-experimental design and case study designs was employed to compare the effect of the metaconceptual activities and traditional instruction and investigate students'…

Today, the use of web-based videos in science classrooms is becoming more and more commonplace. However, these videos are often fast-paced and information rich--science concepts can be fragmented and embedded within larger cultural issues. This article addresses the cognitive difficulties posed by many web-based science videos. Drawing on concepts…

The assimilation and synthesis of knowledge is essential for students to be successful in chemistry, yet not all students synthesize knowledge as intended. The study used the Learning Preference Checklist to classify students into one of three learning modalities--visual, auditory, or kinesthetic (VAK). It also used the Kolb Learning Style…

Teachers using interactive whiteboards (IWB) effectively can engage and motivate students with a range of digital resources to explore science's role in making sense of our world and to construct knowledge of key scientific concepts. The case study research described in this paper illustrates how interactive pedagogies in the IWB classroom were…

This paper describes the design and implementation of a tool for experimenting with mobile robotics concepts, primarily for use by children and teenagers, or by the general public, without previous experience in robotics. This tool helps children learn about science in an approachable and interactive way, using scientific research principles in…

In this paper I respond to Long's paper in which he uses an ethnographic snapshot of a rally of scientists against the perceived "dumbing down" effect of the new Answers in Genesis Museum in Kentucky to raise educational concerns about the effects of creationist influence on the science curriculum in American schools. In my response I…

This book is a collection of 28 experiments that are not meant to have any practical purpose. Each experiment, however, illustrates a scientific principle and enables students to discover how scientific facts and theories apply to seemingly useless experiments. Each experiment includes a list of materials, a series of steps, an explanation of the…

With the emergence in physics of relativity and quantum theories in the first decade of this century a paradigm shift took place from a predominantly mechanistic to a dynamic world view. This shift formed the basis of the New Science Movement, including the new physics, in the 1970s. The movement is international, interdisciplinary, dynamic, and…

Science is a subject that offers itself to a variety of instructional modes. Many educators have suggested that teachers need to make science more real and interesting for students. This activity is a Christmas play that allows students (grades K-6) to celebrate both the holiday season and the wonders of science. While participating in the play,…

Indicates that science instruction should emphasize that many of our explanations of natural phenomena are just mathematical models of what is observed, and often an explanation that can be conceptualized is not available. (GS)

Some designs of simple wave demonstration devices have been described in this journal and elsewhere. A new simple model can be built using only dowels, binder clips, and loops of thread. Not only can it be easily assembled, stored, or disassembled, but also all the students in a class can cooperate in its building by connecting successive pieces…

Particle production and solids processing are essential components of the contemporary process industries. Crystalline solids represent a large and important segment of this manufacturing sector. Chemical engineers, especially in the United States, have historically abandoned this subject, leaving it to pharmacists, physical chemists, material…

At a recent symposium concerning the teaching of solid state chemistry in the classroom, many educators indicated that important areas of solid state chemistry were being neglected in college curricula. (RH)
